- kube-apiserver: the `StorageObjectInUseProtection` admission plugin added the `kubernetes.io/vac-protection` finalizer to the given VolumeAttributesClass object when it is created if the feature-gate `VolumeAttributesClass` is turned on and `storage.k8s.io/v1beta1` is enabled.

## Código assíncrono { #asynchronous-code }

Código assíncrono apenas significa que a linguagem 💬 tem um jeito de dizer para o computador / programa 🤖 que em certo ponto do código, ele 🤖 terá que esperar *algo* finalizar em outro lugar. Vamos dizer que esse *algo* seja chamado "arquivo lento" 📝.

Então, durante esse tempo, o computador pode ir e fazer outro trabalho, enquanto o "arquivo lento" 📝 termina.

FastAPI admite dependencias que realizan algunos <dfn title='a veces también llamado "código de salida", "código de limpieza", "código de teardown", "código de cierre", "código de salida del context manager", etc.'>pasos adicionales después de finalizar</dfn>.

Para hacer esto, usa `yield` en lugar de `return`, y escribe los pasos adicionales (código) después.

/// tip | Consejo

Asegúrate de usar `yield` una sola vez por dependencia.
